JESSE E. FOLK, OF BROOKLYN, NEW YORK, ASSIGNOR TO THE AKTIEBO- LAGET SEPARATOR, OF STOCKHOLM, SVEDEN.

CENTRIFUGAL CREAM ER.

SPECIFICATION forming part of Letters Patent No. 504,430, dated September 5, 1893. Application tiled April 25, 1892. Serial No. 430,577. (No model.)

To all whom it may concern.- Be it known that I, JESSE E. FOLK, a citizen of the United States, residing at Brooklyn,inl

the county ofKings and State of New York, have invented new and useful Improvements in Centrifugal Creamers, of which the follow-V ing is a specification.

My invention relates to that class of centrifugal separators which are used for separating acompound liquid into its constituent liquids of different specific gravities, particularly for separating milk into cream and skim milk, and which are provided with upright partitions or division plates in the liquid space of the bowl, whereby the liquid is divided into thin layers.

The object of my invention is to improve the construction of these partitions or division plates in such manner as to increase the separating capacity of the bowl.

In the accompanying drawings consisting of two sheets:-Figure 1 is a vertical section of a centrifugal separator provided with my improvements and having the corrugations of each division plate arranged obliquely in opposite directions. Fig. 2 is a fragmentary horizontal section in line w--x, Fig. l. Fig. 3

is an elevation of one of the division plates having its two oblique sets of corrugations separated by a plane surface. vertical section of a centrifugal separator having the division plates provided with vertical corrugations. Fig. 5 is a fragmentary horizontal section in line y-y, Fig. 4.. Fig. 6 is a vertical section of a centrifugal separator having the division plates provided with oblique corrugations. Fig. 7 -is a fragmentary elevation of the division plates represented in Fig. 6. Fig. 8 is a vertical section of a centrifugal separator having the division plates provided with horizontal corrugations. Fig. 9 is a fragmentary elevation of the division plates represented in Fig. 8.

Like letters of reference refer to like parts in the several figures.

A represents the bottom of the bowl, B the side or peripheral wall thereof, and C the cover provided with a contracted neck c and secured to the peripheral wall by a screwthreaded iiange or other suitable means.

D represents one of the skim milk pipes Fig. 4 is a secured to the cover on the inner side thereof and opening with its lower end near the peripheral wall and penetrating with its upper end the contracted neck.

E represents a false bottom resting with its peripheral portion on the'bottom of the bowl and provided with a raised central feed cup e.

F represents the upright division plates secured with their lower ends to the false bottom and with their upper ends to an internal cover G, so that the internal division contrivance composed of the false bottom, the division plates and the internal cover can be inserted and removed as a whole. The internal cover is provided at its center or apex with an opening of about the same size as the internal opening or bore of the neck, and in its periphery or outer edge with notches g through which the skim milkI passes upwardly. The false bottom is provided between its inner and outer edges with a circular row of openings e through which the milk enters the spaces between the upright division plates. The division plates may be arranged radially or tangentially, as may be preferred, but in either case they are arranged substantially parallel with the axial line of the bowl, and upright when the axis of the bowl is arranged vertically.

In the construction of the division plates represented in Figs. 1 and 2, the plates are provided wit-h corrugations h which are arranged in the upright middle portion of each plate or between the inner and outer edges thereof. This middle portion of each plate is located in that zone of the liquid space which is occupied by the full or whole milk and in which the principal part of the separation of the milk into cream Vand skim milk takes place while the inner and outer plane portions of each plate are located respectively in the zones which are occupied by the separated cream and skim milk. The corrugations h ascend from the middle of each plate inwardly and outwardly, whereby the currents of separated cream and skim milk are conducted not only inwardly and outwardly, but alsoat the same time upwardly or toward the discharge end of the bowl, whereby the delivery of the separated particles into the cream and skim milk zones and the progress` IOO ive movement of the separated constituents toward the outlets is greatly expedited. The corrugations themselves form troughs in which the particles of each constituent liquid accumulate and by which these accumulations are conducted to their respective zones, thereby avoiding conflict of the currents passing in one direction with those passing in an opposite direction and increasing the separating capacity of the bowl accordingly.

In the construction of the plate represented in Fig. 3, the two sets of oblique corrugations h h' in the same plate are separated by an intervening plane portion h2 of the plate. In the construction of the plates represented in Figs. 4 and 5, the plates are provided with Vertical corrugations h3, and these corrugations increase in size toward the periphery of the bowl. In the construction of the plates represented in Figs. 6 and 7, the corrugations h4 are arranged obliquelyin the same direction over the entire surface of each plate. In the construction of the plates represented in Figs. 8 and 9, the corrugatious h5 are arranged horizontally in each plate.

I do not wish to claim in this application the construction of the division contrivance composed of the false bottom, the division plates and the internal cover, because that subject matter is claimed in another applica tion filed April 25, 1892, Serial No. 430,576.

I claim as my inventionl. The combination with a separator bowl, of corrugated division plates arranged verti cally within the bowl, substantially as set forth.

2. The combination with a separator bowl, of vertical division plates provided each with two rows of corrugations inclined in opposite directions, substantially as set forth.

3. The combination with a separator bowl having a closed bottom and a contracted discharge neck at its top, of.` vertical division plates each provided with two rows of corrugations inclined toward the neck of the bowl, substantially as set forth.

Vitness my hand this 18th day of April,

JESSE E. FOLK. Witnesses:
